标题:金属三氟甲磺酸酯促进内酯氢解成羧酸的综合研究:从合成和机理的角度
摘要:内酯直接氢解为羧酸(即不接触羰基的c烷氧基-O键的氢解)通常是困难的,因为当前使用布朗斯台德酸作为催化剂的策略通常需要苛刻的条件,例如高温和高温h 2压力.在此,我们报告了已开发的无溶剂催化转化方法,其中w(otf)6被认为可以促进氢解过程.该策略可以在特别温和的条件下(例如,反应温度<150oc和1 Atm H 2的条件下)有效地将内酯氢化为羧酸),并显示出较宽的基材范围.另外,该催化方案可以进一步应用于作为可再生聚合物的聚羟基链烷酸酯的氢解成相应的直链羧酸.随后进行了广泛的机理研究,密度泛函理论计算揭示了一种反应模式,包括在w(otf)6的帮助下c═o键的完全裂解催化剂.此外,通过电喷雾电离质谱已成功检测到该机理中产生的关键中间体,即具有otf部分的moiety.通过与布朗斯台德酸催化体系的比较,研究证实了otf部分的存在可以显着降低与重排和消除过程相关的障碍.同时,重点放在阴离子发挥
